Definitions

  • the invention relates to the field of single-use paper rolls used in particular by the public at large or by groups and known under designations such as toilet paper, toweling rolls, all-purpose wiping towel rolls, or hand towel rolls.
  • the product is most often placed in a dispensing device which supports and protects the roll and which performs the function of dispensing the paper.
  • a dispensing device which supports and protects the roll and which performs the function of dispensing the paper.
  • Several important functions of the dispenser include storage of paper, hygiene, and monitoring of consumption.
  • the dispenser and the product which it contains are often regarded as systems. They will be designated as such in what follows.
  • dispensers are relatively high and, except as otherwise provided, the dispenser may be suitable for several types of products. Under these conditions the commercial risk exists of having competing products offered in a dispenser that has been supplied by another dealer.
  • Rolls including necks which operate in conjunction with special supports are also known.
  • a roll without a neck cannot be kept in the dispenser or the door of the latter cannot be closed because of the different space requirement of the roll without a neck.
  • a neck of this type is very effective but its production requires complex conversion equipment.
  • the object of the invention is to provide a simple, cost-effective, and reliable means of making an automatic or semi-automatic dispenser, electric or electronic, for paper in rolls “captive” by using simple, conventional paper adaptation means.
  • the invention aims to optimize these tubes in order to assign an additional function in conjunction with the dispenser in which they are mounted.
  • This function consists of providing the tube with electric conduction properties, thereby enabling this tube to perform the function of circuit breaker inside the dispenser provided for this purpose.
  • the object of the invention is a system for distribution of a product rolled on an element, such as a tube, this product defining a structure such as that of a cylinder and the system in question comprising in particular:
  • the tube comprises an electrically conductive element designed to operate in conjunction with a frame element so that the two together make up an element of an electric circuit.
  • the invention relates preferably to the electrically “conductive” function assigned to the tube.
  • the current-conducting element may consist of a layer of conductive material in contact with all or part of the interior and/or exterior surface of the tube.
  • the conductive layer in question may be of a thickness ranging from a few microns to around 1 millimeter.
  • the invention is suitable for being applied in various technical solutions.
  • the tube is made up of a cardboard cylinder coated on the inside with a layer of conductive material, such as copper or aluminum.
  • the layer of conductive material may consist of a strip of metal glued to the surface of the cardboard cylinder in question.
  • the conductive element consists of a network of metal wires woven or knitted together.
  • the conductive wires preferably may have a diameter of the order of 50 microns.
  • the conductive element may comprise a network of interwoven polymers or elastomers to which are applied conductive elements, such as carbon, silver, nickel, copper, or aluminum.
  • the conductive element consists of a layer of conductive material made up of a coat of paint or ink including conductive particles (or charges).
  • the system claimed for the invention comprises at least one element the purpose of which is to ensure electric connection of the tube and the frame.
  • This element may be in the form of a connector having a conductive contact force fitted into one end of the tube.
  • the invention also relates to a conductive tube to be used in a roll dispensing system.
  • FIG. 1 is a diagram of equipment for production of conductive tubes as claimed for the invention
  • FIG. 2 is a diagram illustrating a means of forming a tube by adhesion in one embodiment of the invention
  • FIG. 3A is a diagram illustrating the forming of a tube as claimed for the invention by rolling
  • FIG. 3B a simplified section of the thickness of a tube claimed for the invention
  • FIG. 4 is a photograph of the interior of a tube partly coated with a conductive strip
  • FIG. 5 is a photograph of the interior of a tube coated in its entirety with a conductive strip
  • FIG. 6 is a flow chart of an electric circuit of a dispenser comprising a tube as claimed for the invention.
  • FIG. 7A is made up respectively of a cross-section and a longitudinal section of a first embodiment of a dispenser projection
  • FIG. 7B is made up respectively of a cross-section and a longitudinal section of a second embodiment of a dispenser projection.
  • FIG. 1 illustrates a tube production assembly intended specifically for the dispensing system claimed for the invention. More specifically, FIG. 1 relates to one embodiment of such a tube.
  • One or more strips 10 of cardboard are unrolled from tone or more spools (not identified by reference numbers) simultaneously with a strip of conductive material 11 .
  • the latter may be intrinsically conductive or may be coated with a conductive material.
  • aluminum, copper, nickel, among others, are to be selected as conductive materials.
  • the strips 10 make it possible to rigidify the tube ultimately obtained and-to impart a certain thickness to it.
  • the different strips 10 , 11 are taken to a gluing station 20 , an exemplary embodiment of which is illustrated in greater detail in FIG. 2 .
  • the strips, 10 , 11 are positioned so as to be side by side in the same horizontal plane and while in this position are taken to a spindle 30 on which they are rolled simultaneously as is explained below in connection with FIGS. 3A and 3B .
  • a drive belt 40 ensures guiding of the strips 10 , 11 around the spindle 30 as well as securing of these strips against it in order to ensure cohesion of the strips to each other and shaping of the strips.
  • the strips 10 , 11 form a cylinder, or hollow tube, preferably provided on the inside with a conductive layer.
  • FIG. 2 presents an example of a means 20 of gluing at least one of the strips 10 , 11 .
  • the means is itself known, so that only a brief description of it will be given here.
  • the strip 10 to be glued comes to a first cylinder 21 serving to tighten and guide the strip.
  • the strip 10 then comes in contact with a second cylinder 22 serving to transfer glue.
  • a third cylinder 23 positioned downstream from the second cylinder 22 in the direction of advance of the strip 10 provides for application of glue to the second cylinder 22 .
  • the three cylinders 21 , 22 , 23 have parallel axes perpendicular to the direction of advance of the strip at the level of the gluing means- 20 .
  • a tank 24 positioned below the cylinders contains the glue.
  • a scraping knife 25 or any other means permitting control and limiting of the amount of glue is provided, preferably near the outlet end of the strip.
  • glue on one of the strips 10 , 11 may, of course, be considered without going beyond the framework of the invention; nozzles may also be used to project glue onto the strip or strips.
  • a glue of the hot-melt type may be provided, or a two-sided adhesive strip (pre-glued), may be brought into contact with at least one of the strips 10 making up the rigid structure of the finished tube.
  • FIG. 3A presents a top view of a diagram of the process of winding of the strips 10 , 11 around the spindle 30 .
  • the strips 10 , 11 arrive at an angle ⁇ of a value other than zero relative to the plane perpendicular to the axis of the spindle. They are pulled around the spindle 30 by the belt 40 .
  • FIG. 3B section AA shows the arrangement of the strips.
  • a layer of glue C is deposited on the exterior of the (cardboard) strip 10 to ensure joining to the internal conductive strip 11 .
  • Strips 10 , 11 are laterally displaced.
  • Arrows F in FIG. 3A indicate the force of clamping of the belt 40 ; as has already been pointed out, this force ensures good joining and cohesion of the strips 10 , 11 to each other.
  • the two strips 10 , 11 joined to each other form a conductive cylinder which is then cut into individual conductive tubes 50 , such as those shown as examples in the photographs in FIGS. 4 and 5 .
  • the tube 50 is partly coated on the inside with a conductive layer 50 c made up of the strip 11 in the embodiment described in the foregoing.
  • the interior surface of the conductive tube 50 is covered in its entirety-with a layer of conductive material 50 c.
  • this conductive layer may be of a thickness ranging from a few microns (around 10) to around 1 millimeter.
  • the structure 10 which ensures rigidity of the tube 50 may be of a thickness of around 1 millimeter to around 3 millimeters.
  • the conductive layer 50 c may be positioned on the inner and/or outer structural layers and/or inserted between the structural layers (such as those of cardboard 10 ) of each tube.
  • the width of the conductive strip 50 c may or may not equal that of the strips 10 .
  • the conductive element may consist of a network of conductive wires interconnected by weaving or knitting.
  • Non-woven is here understood to mean an array of wires and/or fibers assembled so as to form a bundle whose weight may range from approximately 35 to 50 grams per square meter.
  • a “wire” is of a length of a few centimeters to several meters or even several hundred meters, while a “fiber” may be of a length of several millimeters to around 100 millimeters. These lengths are obviously given only by way of illustration for the purpose of clarifying the different terms used.
  • the wires may be of nickel and have a diameter of around 50 microns.
  • the layer or coat thereby formed is associated with a rigid structural element by any known method, such as by lining as specified in the foregoing with reference to FIG. 1 .
  • Another embodiment of the conductive tube 50 claimed for the invention may consist of producing a conductive element 50 c by applying a coat of paint or ink specifically containing conductive particles.
  • the particles currently are of a diameter of the order of a few millimeters, while the layer may be of a thickness of a few microns to 1 millimeter.
  • the electrically conductive tubes produced in this manner are designed to be incorporated into motor-driven automatic or semi-automatic electronic or electric dispensers.
  • the modifications needed for such dispensers to enable them to operate with tubes of this type are minimal. In effect, it suffices to modify the electric system so as to have an open circuit when such a tube is absent and a closed circuit when a tube is present.
  • the conductive tube in this instance performs the function of a “circuit breaker”.
  • FIG. 6 illustrates the principle of operation of a dispenser claimed for the invention.
  • the conductive tube 50 is brought into contact with two connectors 60 provided with contactors. Electric power may come from a battery 70 or a power grid. This energy source controls the dispenser for performance of operations such as automatic paper feed, detection of jamming, and so forth.
  • a known automatic dispenser is described, for example, in patent applications EP 1 232 715, EP 1 231 823, EP 1 230 886.
  • Dispensers of this type comprise a frame the purpose of which is to hold and place in position one or more rolls of paper, means of dispensing the roll or rolls of paper, and means for control of the dispensing means.
  • control means react to electric sensors.
  • proximity sensors designed to detect the presence of a user in the vicinity of the dispenser make it possible to dispense a specific length of paper.
  • a roll with conductive tube such as that described in the foregoing, is particularly well suited for such dispensers.
  • Connecting elements are needed in order to effect contact adaptation of rolls such as are described in the foregoing in an automatic dispenser of this type.
  • FIGS. 7A and 7B are cross-sections and longitudinal sections respectively of connectors 60 capable of operation in conjunction with and of coming in contact with the conductive tube 50 .
  • Each connector has a cylindrical area 61 designed to be brought into contact with the inner wall of the tube 50 , as well as an end cap 62 which rests against one of the ends of the tube.
  • the connector 60 preferably is force-fitted into the tube 50 .
  • the cylindrical area 61 of the connector 60 is covered externally by a conductive cylinder 63 which, when the connector 60 is positioned at one of the ends of the tube 50 , comes in contact with its inner surface, thereby closing the electric control circuit as shown in diagram form in FIG. 6 .
  • the cylindrical area 61 of the connector 60 is partially covered by a contactor 64 .
  • the conductive element ( 50 c ) may consist of a wire element joined by any known means to the rigid structure 10 of the tube, the wire element being positioned so as to come in contact with the contact elements 64 of the electric circuit of the dispenser.
